I got the chalk that washes out, not irons out and used a leaf stencil. the stencil had little sharp areas that the pounce pad kept catching on when I just wiped it across as directed.
i ended up "pouncing" mine. that did work. i have yet to quilt it yet so don't know how it will hold up while doing that. next time i refill, i will go ahead and order the chalk that irons off.
oh, i did spray with hair spray as some quilters suggested.
